Scientists from our Department of Biology & Biochemistry have developed a new technique that will streamline biomedical research and could in the future prevent genetic diseases before the moment of conception.

The genetic material DNA can survive a flight through space and re-entry into the earth's atmosphere—and still pass on genetic information. A team of scientists from UZH obtained these astonishing results ...

(Phys.org) —Cheng Qin of Sichuan Agricultural University in China and his colleagues have sequenced the genomes of wild and domesticated peppers and found that a large percentage of the pepper genome consists ...

Since its discovery, researchers have hailed Cas9—a protein "machine" that can be programmed by a strand of RNA to target specific DNA sequences and to precisely cut, paste, and turn on or turn off genes—as a potential ...

The Sherpa population in Tibet is world-renowned for their extraordinary high-altitude fitness, as most famously demonstrated by Tenzing Norgay's ability to conquer Mount Everest alongside Sir Edmund Hillary. The genetic ...

Bacteria living in the Gulf of Mexico beaches were able to 'eat up' the contamination from the Deep Water Horizon oil spill by supplementing their diet with nitrogen, delegates at the Goldschmidt conference will be told today, ...

Interbreeding between escaped farmed salmon and their wild counterparts is a major headache for the aquaculture industry. Now Norwegian fish farming companies are raising one million sterile salmon in sea ...

Baker's yeast is a popular test organism in biology. Yeasts are able to duplicate single chromosomes reversibly and thereby adapt flexibly to environmental conditions. Scientists from the Luxembourg Centre ...

(Phys.org) —In 1958 a group of scientists working in Denmark made the striking observation that bacterial cells are about twice as large when they are cultured on a rich nutrient source than when they are ...

Using powerful computer models, researchers from Brown University have shown for the first time how different types of red blood cells interact to cause sickle cell crisis, a dangerous blockage of blood flow in capillaries ...

A new study challenges the orthodoxy of microbiology that in response to environmental changes, bacterial genes will boost production of needed proteins and decrease production of those that aren't. Researchers ...

Genetic disorder

A genetic disorder is an illness caused by abnormalities in genes or chromosomes. While some diseases, such as cancer, are due in part to a genetic disorders, they can also be caused by environmental factors. Most disorders are quite rare and affect one person in every several thousands or millions. Some types of recessive gene disorders confer an advantage in the heterozygous state in certain environments. A haploid cell has only one set of chromosomes. A diploid cell has two sets of chromosomes. In human, the somatic cells are diploid, and the gametes are haploid.
